The Opportunity: We are looking for a highly capable Software Engineer to join our Powered team and contribute to the core libraries that power every Speedtest client, and to the SDKs used by third-party device manufacturers and application developers.

• Solve for reliability, flexibility, portability, and code reuse.
• Collaborate on architecture, technology choices, and interactions with other core components such as front end code, backend APIs or our distributed server network.
• Integrate analytics to ensure optimal performance of deployed code.

Job Requirements:* 4+ years of software development experience, with a solid foundation in data structures, algorithms, and design patterns.

• Experience with Android using Kotlin or Java
• Strong understanding of networking fundamentals (IP, TCP/UDP, HTTP/S, WebSocket).
• Experience writing unit, integration, load and stress tests.
• Proficiency with collaborative development workflows (branches, PRs) and continuous integration practices.
• Strong time management skills and a self driven work ethic.
• Excellent debugging and troubleshooting skills.
